  • Patent number: 4539303
    Abstract: An improved process for recovering energy via an expander turbine axial flow gas compressor set which utilizes hot regeneration gas recovered from the regeneration of fluidized catalytic cracking catalyst, and during turndown conditions when the output of the gas compressor is required to be increased by an excess amount to prevent surge and the excess amount is normally vented to the atmosphere prior to entering the regenerator to prevent afterburn, the process including the steps of:(1) adjusting air compressor air rate set point to at least 10% above surge; thereby(2) increasing air rate to an amount in excess of regeneration requirement;(3) flowing all air compressed to the regenerator;(4) by use of complete combustion catalyst, oxidizing essentially all coke to carbon dioxide,(5) driving the expander with all the hot flue gas produced and thereby;(6) driving the motor-generator thereby generating electricity.

  • Patent number: 3966587
    Abstract: An improved method is disclosed for controlling the temperature of the fluidized dense catalyst phase of the regeneration zone in a fluid catalytic cracking unit, wherein the coke laydown in the reaction zone is at a level such that the coke concentration of the partially deactivated catalyst from the reaction zone is not sufficient to provide the heat required to maintain the controlled temperature in the fluidized dense catalyst phase of the regeneration zone. In this method, torch oil is added to the partially deactivated catalyst in the spent catalyst transfer line in an amount such that the catalyst charged to the regeneration zone contains sufficient combustible material to provide the heat necessary to maintain the fluidized dense catalyst phase of the regeneration zone at the controlled temperature.
